Best Answer: I'd say about 10-15 mins walking at a relatively average pace!! Fastest time to run a mile is around 4 minutes. The average time to walk a mile is 12 minutes, so half a mile would be 6 minutes. i walk a mile every morning in 15-20 minutes, so probably 10 minutes. At a semi rapid rate about 7 1/2 minutes.
Allergy is one of the most common causes for burning sensation in nose. It can be a seasonal allergy or an allergy associated with pollution. Certain gases and smoke released from chemical substances may pollute the air and find their way into the nose and air passages.
A burning sensation in the throat could also be the result of drainage from the Eustachian tubes. The Eustachian tubes are a pair of passageways that link the back of the nose and throat to the middle ear.
